Z1 Oil Cooler
 

Any update on this issue? I had Z1 install a 25 row oil cooler and now have this whining noise also! What do I do??????

I am too lazy to try this but did talk to dustin at z1 about putting rubber grommets inbetween all of the bolts that mount the cooler to the car. He said they did some similar testing and it is still there. There isn't really anything you can do about it. It has to do with the pulsation of oil through the cooler.

Thx for the quick reply. I will rep u as soon as I get to a computer.

So this is just a sound thing and no actual harm is being done to the oil pump?

No harm done. I have driven mine for 14000 miles. Is yours thermostatically controlled?

Yes mine has it. Thx bro this makes feel a lot better

cool deal no prob.

I had forgotton about the whine noise of the past. Good to know it's still only a feature that we have to live with...

Will be installing my Z1 25 row cooler in a couple of weeks.

Make sure you fab a cover plate when you put it on...just sayin....

^Got one made up , thanks. btw Z1 is shipping their oil coolers with the rubber mounts. At least from orders placed on black friday onward.

oh cool thanx for the info. I talked to Dustin and he said that even witht he rubber mounts that it still whines, on some cars it doesn't. It can get pretty frustrating though. Oh just for a tip, you might want to grind down the wall on a deep 1in socket so that when you torque the adapter to the oil filter bolt/housing that it grips well, and make sure its a 6 pt so you don't chance stripping the head. I think it calls for 40ft lbs.

Thanks Roy for the excellant tip on the 1" deep socket mod. :tiphat:

Just a quick update on my Z1 25 row winning situation. I spoke to Jon at Z1 and he said that they will ship out a different line to me that will solve the problem. So I'm hoping it does, not too sure that I can get used to that sound. But this is what happens when we mod our cars.

Hopefully I have this "different line" that John (Z1) is referring to.... I guess it's car specific from what I read previously...that not all cars have the whine noise after oil cooler install.

Edit: just curious...when did you purchase your Z1 kit?

two weeks ago when i drove from florida to Z1, they did the install too

Let me guess, you got the hoses with the shrinkwrap sleeving on them. Is that the different hoses that John was referencing to? If so I have the same and it still whines. I wish I could hit this on the head and solve it....frustrating
